在物理上,从理论到应用的历程可能要数十年。甚至最快的进展,也常以年计。因此在高温领域的超导体(即通电流时无热损失,无须冷到接近绝对零度)的神速进展甚至使乐观的研究工作者为之目眩。三周前材料专家预言,新的超导陶瓷要以月或年计才能制成导线。上星期,在Illinois′Argonne国家实验室的科学家们却做出了这种导线。在1800°F烘焙的腊状陶瓷土作成的导线是脆弱的,仅能短暂时间通电。但这给物理学家们以希望能够制成强而柔软的超导线,为电工业开创新纪元。
Physically, the journey from theory to application can take decades. Even the fastest progress, often in years. So even the optimistic researchers dazzled the rapid progress of superconductors in high temperature fields, ie, with no heat loss through the current flow and no need to cool to near absolute zero. Three weeks ago, materials experts predicted that the new superconducting ceramic should be made in a month or years to make wire. Last week, scientists at the National Laboratory in Illinois’ Argonne made the wire. The wires made of waxy ceramic clay baked at 1800 ° F are fragile and can only be energized for a short period of time. But this gives physicists the hope that they will be able to make super-soft superconducting wires, setting a new era for the electric industry.
